I imagined the mouse based on the photos quite small. In fact, it is large and can be operated very handy. It is well made and is kept completely black except for the silver colored stripes. Overall, this mouse has 7 buttons. Several of them can be configured as desired. In addition to the standard buttons there are on the top of a button, to jump straight back into the center of the screen. A button to switch between 1,000 or 1,500 dpi is also available. Very good, I like the two buttons on the inside left. These are operated with your thumb. They can be used to move forward in the browser on the called websites and jump back. I find this incredibly useful keys and got used to it quickly. These two "thumb buttons" sit on a movable plate. This plate can at request about one cm are extended from the mouse to the outside (see product photos because poorly explained). Makes sense if you have larger hands.
The mouse works without drivers. I use Windows 7. Once the receiver is in USB output connected and the mouse is turned on, the computer is the mouse. Those who want to prove the keys themselves differently, should install the little tool on the computer. The handling of the program is to be understood in English, but quite simple.
I like this optical mouse, because it fits comfortably in your hand and the buttons respond quickly. No cramped hands, even after hours of use. Contrary to my previous mouse, this has a neutral smell here. It stinks not to any chemical odors. Therefore, I am also very satisfied!
